In the drawings, I have shown what is ordinarily termed an: all celluloid v o r combrid'ge and riins 015 ly in position ophthalmic frame comprisinga pair of composition lensrims'lo'having the'endpieces 11 for the temples.12. The rims' 10 being connected by an integral bridgeinember 13. Ordinarily a moiinting'of this kind has been made entirelyof composition material, either 7 without any metalentering'into it, or else with metal'only at the endp'ieces orjointsto aid in uniting the parts'and con- This is the appear- M j by reference to Figure 4:, from'which it will;

ance also presented by the present mounting. The difference however, will: lee-understood be seen that contained within each "of the 1-0; i'sa metallic frame 1 1 and passing centrally through the br'idge 13 is ametallic bridge 15 making a complete metallic frame contained Within the non-rmr-zta llic frame.

This metallic frame terminates as at 1G to form a split metal rim or frame llk I e 'In the formation of the mounting the rim portions 10wareconstructedwith-the interiorgrooves as at'l7- for themctal lens rims 14 While the bridge is in unbentjform.

The bridgeis drilled or the like to formzthe recess'18, as shown in Figure 2 the size of 'theirecess being; just sufiicientto receive-the.

metallic bridge portions .15. The bridge consists of a tubular lug member 19 mounted on theperiphery of one of themetallic lens rims l0 and a, second lug member pro I videdl with the stud, or rod portionf22 adapted to fit in the=necess 28of the tubular- "lug member 19, This second lug member 20 being mounted von the periphery oi" the other metallic lens rim 14-. It 'willbe readily seen thatvwhen the bendis made toformthe v bridgev13 that the metallic bridge member 1'5-Willbe securely united and there will be no chance for the; parts to slide out of en.-

gagement. v c

In assembling this particular. construction 7 one of the lug portions carried. by the rim 1-1 memberl is slid intothe recess =1-8 from the ."pandedso that the lenses may be inserted metallic is slid from one side intothe recess 18 and the.- met'allic 7 lens rim 14* is positioned. in the groove" 17 of the composition frame 10.. The second lug portion carried by the second rim opposite side, the stud 22 entering-V the. recess 18 thus uniting the metallic rim members 14- and positioning the second rimmember '14 Wit-hill, the frame portion 10.

These metallicrimportions 14 are left split. with a space'between the ends-as at 16 to enable the composition framesftozbe enin the lens'grooves-24c formed in the rim portions 14. 1 V r WVhen: the bridge 13 with the inserted metallic bridge 15 is bent toshape asshown in Figure 5 it'isapparent'that the bending of the portions 1-9. and 20 and the, stud 22 Will lock the stud in the recessIS'sothat the two metallic rims 14 cannot come apart. 7

The advantage of making the metallic rims 14 in: tvvoparts-is; that they-may be inserted in 'the composition" frame, onepartv from each side, and locked in place by-the bending of the bridge to shape. -I Iitherto it hasbeenimpossible to insert a complete metal-hcframe Within a composition frame -witho'ut splitting' the composition; frame.

This invention therefor provides a: simple, eflieient and econoinieal methodl of placing a metallic frame W thin a composition one 7 desired from ,center; i r

without marring the compositionframe, also it provides easy access in preparing the 'composition" frame for the metallic onein that the recessl'8 in the bridge may be bored f Inaaa trunkin the manu badge 15] each side, meeting inthe of a stud and recess'member as shown in.

Figure 3, the parts of the bridge may be [overlapped'as in Figure 7, or half lapped as in Figure 9 with the serrations 25. Serra tions maybe used on. the, outside alsoaas showninrFigure la. Insteadof leaving a space between'the endsas at 16 Figures 3 and aithe-end's may be bent as at 26 Figures 16 and; 18-and se cured in a recess 27 of the endpiecell.v For 8, or the composition en'dpiece may :be split atv 31 Figure l9and the temple 12; attached to one of the endpiecesections by, the hinge 30 and the-twosections'of the split -endpiece secured together by a, screw 32 engaging a metallic bushing 33 in one of, the, sections. vIn this construction the. lens may be in serted in therims by loosening the screiv32 without: disturbing the-temple connection."

From the foregoing description of -the manufacture of parts and the arrangement of same lt Wlll. be seen that simple, inexpen- 10 sive and efficient means have been provided}, 7

to carryout the objects of the invention and to provide-a frame of composition reinforced with a. complete frame" of metal without marringl'or separatingthe composition frame. v I Having described the invention I claim;
